Nitrogen

Agronomist Notes

I’m not certain, but there’s some chance that sample #12 has something going on with erroneous sampling/analysis. The CEC for that point is very high relative to the rest of the field. Also, showing very low pH.

See ‘Supporting Information > Nitrogen Management’ for guidelines on nitrogen management in Indiana.

Phosphorus

Agronomist Notes

Much of the field is has sufficient P levels, but the SW edge of the field and Eastern finger could use some fertilizer or manure application.

See ‘Supporting Information > Phosphorus Management’ for guidelines on phosphorus management in Indiana.

Potassium

See ‘Supporting Information > Potassium Management’ for guidelines on potassium management in Indiana.

Lime

Agronomist Notes

The eastern finger of this field has very low pH levels. Certainly, this is your most pressing issue for this field & where you’re most likely to see a return on investment. Do not put out more than a couple of tons of lime on this field at one time, although the recommend suggests such. If you do want to make a VRx application to this field, let me help you amend this prescription layer to rates safe for a one-time application.

See ‘Supporting Information > Lime Management’ for guidelines and resources for liming in Indiana.

Phosphorus

Agronomist Notes

This field has very low P levels according to the soil test (9-12 ppm), which would be classified as deficient by Purdue University (<20 ppm). This suggests that you are likely to see a yield response from adding either fertilizer or manure to this field.

Agronomist Notes

The pH on this field looks fine at this measurement, but it is bordering on too low for optimal nutrient availability in corn & soybean. Either apply the 1 ton for the following cycle, or test again in the next year or two.

Agronomist Notes

The conditions are all fairly similar with Bill’s fields - deficient in P and sufficient in K with low pH. However, the pH of this field did test at decent values for optimal nutrient availability by Purdue standards. I would still recommend apply some lime to this field as the base saturation % for hydrogen is greater than ideal.

Phosphorus

Agronomist Notes

Only one sample here, but it says that P level is 8 ppm, which suggests you should consider putting out fertilizer or manure to meet the demand of the incoming crops. Purdue defines deficiency level for P at <~20 ppm P. Might be interesting to treat strips or half of this field (or others) to see if we can visually see responses in treatments.

Agronomist Notes

You would benefit from lime in some parts of this field. I’d caution against applying more than a couple of tons of lime at one time, especially near planting or in no-tillage systems.

Google Earth

Google Earth - Explore past maps of your farm

Step 1: Navigate to the ‘Soil Test Report’ tab at the top of the report.

Step 2: Copy the WGS 84 coordinates of a field from the Survey Summary table.

Step 3: Go to Google Earth (https://earth.google.com) and paste the coordinates into the search box.

Step 4: After Earth directs you to your field, you can utilize the ‘Archive Historical Imagery’ feature to explore imagery from past satellite fly-overs (often going back 1-2 decades).

Terrain Analysis

Risk Rating Description (1-5)

Rating describes risk level of nutrient loss from surface run-off

1 = Low risk of nutrient loss

2 = Low to moderate risk of nutrient loss

3 = Moderate risk of nutrient loss

4 = Moderate to high risk of nutrient loss

5 = High risk of nutrient loss
